All the steps in problem-solving are correctly stated EXCEPT:

• define the problem

• propose some solutions

• determine the best solution

• test and validate the solution

The divide-and-conquer approach is used to:

• define a problem

• validate a solution

• decompose large problems

• create solution algorithms

• constant

• data type

• string

• variable

All the following statements about problem decomposition are correct EXCEPT:

• significant components are input, process and output.

• an IPO chart may be used to delineate the components.

• problems are broken down into simpler sub problems.

• problem decomposition simplifies the problem in step.
